Free movement is a core value, negligible cost or cheap free movement is not. Freedom from border controls - that's it. Given the likely impacts from a heating climate and predictions of economics costs, that probably vastly underestimate, I submit the "tremendous economic recession" comes from not taking adequate action. We'll probably need to end up rationing air travel as the only fair way to achieve the necessary reductions. For me, I simply don't understand economic arguments for inaction. The economic consequences of ignoring the problem are going to be orders of magnitude worse, and a permanent ongoing drag on economies.
